O3/Fenton for the treatment of effluent containing Reactive Yellow X-RG is investigated. The response surface methodology is applied to study the main and interactive effects of the parameters. With the initial dye concentration being controlled at 300 mg L−1, the optimized conditions for wastewater treatment are 3.68, 29.19 and 18.49 mg min−1 for initial pH, mole ratio of [H2O2]/[Fe2+] and ozone dosage, respectively. The regression quadratic model well describing the degradation efﬁciency of O3/Fenton process is...

Combining bioassays and analytical chemistry screening is a powerful approach to assess organic micropollutants which are the main contributors to toxic potential in complex mixtures of treated wastewater (TWW). The aim of this study was to perform a comprehensive toxicity assessment of treated effluents using stress response bioassays and then to assess the occurrence of the organic micropollutants which were responsible for this biological response using gas chromatography coupled with a mass spectrometry...

A microwave-assisted extraction method for the determination of 15 alkyl, aryl, and halogenated phenols in sewage sludge and biosolids samples was developed and optimized. The effects of solvent, temperature, time, moisture content, acid, and number of extractions on the recovery of phenols were evaluated. Results indicated that extraction solvent had the greatest impact on the recovery of all phenols while pH had the largest effect on recovery of hexachlorophene and pentachlorophenol. Wet sludge samples were...

The hazardous constituents of cigarette smoke have attracted considerable attention lately, especially with increasing regulation around the world limiting or banning smoking in public places – and even in private cars if children are present.
From an analytical perspective, however, there is much that remains to be learnt about the composition of cigarette smoke, because of its high degree of complexity – tobacco smoke is thought to contain thousands of components across multiple chemical classes...

Beer contains hundreds of organic ingredients, with concentrations spanning many orders of magnitude, and including monoterpenes (C10) and sesquiterpenes (C15). These are aroma-active hydrocarbons found in the essential oils of various plants, including hops, and provide much of the characteristic ‘bitterness’ of the finished beer.
Of the greatest importance for beer is the monoterpene β-myrcene, and the sesquiterpenes caryophyllene, β-farnesene and α-humulene. However, there are...
